The equation is equivalent to 1/cos(2x)-2=sin(2x)/cos(2x). Make the denominator cos(2x) for all terms, we get 1-2cos(2x)=sin(2x). Since cos^2(2x)+sin^2(2x)=1, let cos(2x)=a, substitute sin(2x) by +-\sqrt(1-a^2), and solve the equation with only one variable a. We get a=4/5 or 0, but cos(2x) cannot be 0, otherwise sec(2x) is undefined. 2x=36.9 degrees, so x=18.9 degrees approximately.
Answer:
See below.
Step-by-step explanation:
So we have the expression:
First, factor out the GCF.
The GCF is 2u². Thus:
And this is the simplest it can get.
So we are done :)
1/2+ 9/10+ M= 2
⇒ 7/5+ M= 2
⇒ M= 2- 7/5
⇒ M= 3/5
M= 3/5~
Answer:
42in :)
Step-by-step explanation:
All you have to do is multiply 7x6 because u need to find the area.
but if u wanna find the perimeter u have to add all sides.
area is multiply 2 sides.
Answer:
Rosa is right.
Step-by-step explanation:
Because 3/4 = 0.75
which means 0.75 is greater than 0.25
